It is identical with CENELEC Electronic Components Committee (CECC)14000:1984 “Harmonized system of quality assessment for electronic components: Generic specification: Photomultiplier tubes”. In1991 the CENELEC Electronic Components Committee (CECC) accepted CECC14000:1984 as European Stand
7、ard EN114000:1991. As a consequence of implementing the European Standard this British Standard is renumbered as BSEN114000 and any reference to BS CECC14000 should be read as a reference to BS EN114000. This standard gives the terminology, quality assessment procedures and test and measurement cond
8、itions applicable to the entire family of photomultiplier tubes. Any sectional and blank detail specification dealing with a particular sub-family of photomultiplier tubes required to be used in conjunction with this standard will include those tests that are considered appropriate to the sub-family
9、 and will also give more detailed information relative to the sub-family. This standard is a harmonized specification within the CECC system. Terminology and conventions. The text of the CECC specification has been approved as suitable for publication as a British Standard without deviation. Some te
10、rminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Cross-referenc
11、es. The British Standard which implements CECC00100 is BS9000 “General requirements for a system for electronic components of assessed quality”. Part 2:1983 “Specification for national implementation of CECC basic rules and rules of procedure”. The related British Standards for IEC50 and IEC410:1973

28、ponents Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is to facilitate international trade by the har
29、monization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby accepted by all member countries without further testing. This spe
30、cification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications for PHOTOMULTIPLIER TUBES. It should be read in conjunction with document CECC00100: Basic Rules(1974). At the date of printing
31、of this document the member countries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the UnitedKingdom. Copies of it can be obtained from the addressees shown on the blue fly-sheet. Preface This s
32、pecification was prepared by CECC Working-Group11: Electro-optical devices. In accordance with the requirements of document CECC00100 it is based, wherever possible, on the Recommendations of the International Electrotechnical Commission and in particular on IEC306-4: Methods of measurement for phot
33、omultipliers. The text of this specification was circulated to the CECC for voting in the document indicated below and was ratified by the President of the CECC for printing as a CECC Specification: This specification will be supplemented by blank detail specifications applicable to each sub-family
34、of photomultiplier tubes. The CECC Management Committee at its meeting in Copenhagen in March1979 decided that as the German National Authorized Institution would not be implementing the requirements of this CECC generic specification, the text should be published in the English and French versions

44、is the voltage between photocathode and anode. 4) The illuminant A is defined as a source with a colour temperature of 2 856 20K.
